The Complete Naval Combat Pack contains Dangerous Waters, Sub Command, Fleet Command and 688(I) Hunter/Killer: four authentic niche sims that will appeal to wannabe captains and admirals. Strategy First are offering them for the bargain price of £5.88, which will magically appear (in Pounds Sterling) once you've added the product to your cart and typed in the NAVALPACK voucher code.

As pointed out by one of our readers, though, you've only got a limited window in which to download your content once you've paid for it. To be safe, make sure to nab them and back them up as soon as payment is complete!
